BOTTLE-GAPPING MACHINE.

' Application filed. March 2,

To all whom. it may concern Be it known that we, Gnonon C. ADAMS andWILLIA F. ADAMs, citizens of the United States, and residents of SanFrancisco, county of San Francisco, and State of California, haveinvented a new and useful Bottle-Capping Machine, of which the followingis a specification.

The present invention relates to improvements in bottle capping machinesand its object is to provide a cheap and simple device by which crimpedcaps or corks may be firmly pressed on bottles so as to make a good,air-tight connection.

e accomplish this object by means of the mechanism illustrated in theaccompany ing drawing, in which Figure 1 represents a side elevation ofour capping machine; Fig. 2 a sectional elevation of the same along theline 2-2 of Fig. 1, and Fig. 3 a horizontal sectional view along theline 3-8 of Fig. 2.

Similar numerals refer to similar parts throughout the several views.

Referring to the drawings in particular, a standard (1), consisting oftwo upright members (2) and two horizontal members (3) and (4)connecting and bracing said vertical members, is erected 011 a platform(6). The upright members are rectangular plates, preferably of metal,and the distance between them, being constant at their upper parts,widens toward the bottom. The horizontal. members are channels turnedupside down, the legs being connected to the uprights while the websform the braces or struts. The webs extend somewhat outside the uprightsas shown at (7 and are pro vided with vertically alined perforationswhich form a guide for the plunger rod The latter carries at its bottomend a cylindrical head (9), which is provided at its bottom with arecess (11) of sufiicient size toinclose the cap of a bottle, andconverges near the top. The plunger rod has fastened thereto,intermediate of the two horizontal members (3) and (41), two parallellinks (14:) pivoting on a pin (16) extending through the plunger rod.downward from'their pivotal support and are adapted to be verticallyreciprocated by a lever 18, which has a forked end and each prong ofwhich pivotally engages the lower end of one of said links by the pins(17),

These links hang Specification of Letters Patent. Patented Aug, 30, 19211921. Serial No. 449,042.

which latter two are axially alined. The lever (18) has a short arm (19)extending beyond the pivot (17) and this arm is pivotally supported onthe transverse shaft (21) supported in the two upright members (2),while the long arm (22) of the lever is adapted to be handled by theperson using the device. It will be seen that in this manner 011 anupward motion of the long arm (22) the pivot (17) of the link (14) willmove upward on a circular curve and that the vertical motion will beimparted to the plunger rod (8), which, being guided by the horizontalmembers and 1 (4), cannot partake of the lateral motion of the pivot(17). In a similar manner a downward motion of the long arm (22) of thelever (18) will impart vertical downward motion to the plunger.

The device works as follows: The bottle 7 to be capped is placed belowthe plunger and the cap interposed between the plunger and the bottle. Apressure on the long arm of the lever (18) will cause the recess in theplunger head to firmly grip the cap and press it over and around the topof the bottle.

' We claim:

1. A bottle capping device comprising a vertical standard having twohorizontal members, one being above the other, a plunger guidedvertically in' said horizontal members, two registering links pivotallyengaging said plunger on opposite sides anda gaging said plunger onopposite sides and a forked lever having its forked end pivotallysupported in said. standard and its prongs operative-1y engaging saidlinks for imparting vertical motion to said plunger, said plunger havinga cylindrical head at its bottom and a recess in said head adapted toreceive a cap.
